Effective Thermal Conductivity of Lithium‐Ion Battery Electrodes in Dependence on the Degree of Calendering

The thermal conductivity represents a key parameter for the consideration of temperature control and inhomogeneities in batteries. A high‐effective will entail lower gradients thus more homogeneous distribution, which is considered beneficial longer lifetime battery cells. Herein, impact microstructure within porous electrode coating obtained by different compression rates its contact to current collector investigated as both factors significantly determine overall conduction through electrode. effective two graphite anodes lithium nickel manganese cobalt oxide cathodes evaluated at rates. It found that does not have monotone dependence on porosity with changing results show strong correlation adhesion strength, significant resistance between assumed.
